title: Transscleral suture fixation and anterior chamber intraocular lenses implanted after removal of posteriorly dislocated crystalline lenses.
abstract: The surgical technique is described for simultaneous removal of posteriorly dislocated crystalline lenses and implantation of anterior chamber (AC) or scleral fixation posterior chamber (PC) intraocular lenses (IOL) using pars plana vitrectomy. Twenty-two patients underwent this complex operation. Observation time ranged from 2 to 10 months (mean 5 months). Best-corrected post-operative visual acuity was 1.0 in half the patients in the AC group (n = 12), and in 80% of the PC group (n = 10). It was less than 0.5 in 25% of cases in the AC group whereas all PC patients had visual acuity 0.5 or better. In nine cases with pre-operative ocular hypertension, post-operative intraocular pressure became normal, although topical glaucoma therapy was necessary in three patients in the AC group and in one from the PC group. No severe complications were found. Removal of posteriorly dislocated crystalline lens using pars plana vitrectomy and limbal incision is a safe procedure. Simultaneous AC or transscleral PC lens implantation is a good alternative to contact lenses. Visual rehabilitation was good in both groups of patients, although post-operative visual acuity was better after PC transscleral fixation than after AC surgery.
